MySQL, while Loop & comparison with in_array - php

Question

here is the code:
$sql = "SELECT * FROM example";
$query = mysql_query($sql);
while ($array = mysql_fetch_array($query)) {
if (in_array($array['ipsum'], $page1)) {echo "<h2>correct</h2>"; break;}
else {echo "<h2>not correct</h2>";} }
echo "<div id=\"nucleo\"><h3>lorem ipsum</h3><h1>";
echo $page1;
echo "</h1>";
I have a table with 2 rows in the database: first one is lorem the second one is ipsum (both are INT).
The table is manually compiled when it is needed.
What I want to do is to get the second row (ipsum) and create an array. I don't need to echo values of the array, but I need to compare it with a variable ($page1. this variable is a integer number and it changes continuously).
How could I fix it?

Answer 1

I think this should do what you are after. You should look into switching from the mysql functions/driver to the mysqli or PDO drivers.
<?php
$page1 = (int)$page1;//force $page1 to be an int to avoid SQL injections
$sql = "SELECT * FROM example where ipsum = " . $page1;
$query = mysql_query($sql);
if(mysql_num_rows($query) > 0) {
echo "<h2>correct</h2>";
} else {
echo "<h2>not correct</h2>";}
}
echo '<div id="nucleo">
<h3>lorem ipsum</h3>
<h1>' . $page1 . '</h1>';

You are using in_array() to compare two integer values. you should simply use the === operator like so:
$sql = "SELECT * FROM example";
$query = mysql_query($sql);
while ($array = mysql_fetch_array($query)) {
if ($array['ipsum'] === $page1) {
echo "<h2>correct</h2>";
break;
} else {
echo "<h2>not correct</h2>";
}
}
echo "<div id=\"nucleo\"><h3>lorem ipsum</h3><h1>";
echo $page1;
echo "</h1>";

I fixed it this way:
$array = array();
while ($row = mysql_fetch_array($query)) {
array_push($array, $row["ipsum"]);
}
if (in_array($page1, $array)) {echo "correct";}
else {echo "not correct"; }
I realized by using print_r that the array was not really how I though it was. This way above use all the row of a colums to compose the array... array([0] => row1 [1] => row2 and so on.
Thanks everyone for the help...I apologize for not being very clear about my problem.
